NIELS VIGGO DIECHMANN, OF ESBJERG, DENMARK.

SIGNALING APPARATUS FOR THE PROTECTION OF STATIONS ANDBLOCK-POSTS.

To all whom it may concern:

Be it known-that I, N-lnLs VIGGQ DIEGH-' MANN, subject of the King of Denmark, re-

siding at Esbjerg, in the country of Dention early enough, partly on account of shortage of men and partly because fog and snowstorms may occur suddenly.

The apparatus being very simple and acting with certainty, it may be used in all cases when it is desired to cause a train to stop at a certain point beyond stations and block posts, and consequently, its field of usefulness and adaptability is much wider than that of the torpedo signals.

The apparatus causes a bell placed on the locomotive to sound and, thereby, the engineman is warned at once to stop thetrain.

The apparatus is divided into three parts, namely a station apparatus, consisting of a winch and having its place in a signal house, a line apparatus located in the ballast to the right of the right track rail, in the direction of the travel, and a locomotive apparatus actuated, when the train is passing, by the line apparatus adjusted in its stop-position, and thus producing an audible signal.

One construction of the apparatus of the signaling device according to the invention is shown in the accompanying drawings, Figure 1 representing a vertical section through a portion of the station apparatus, Fig. 2 a horizontal section along the line 11-11 on Fig. 1, Fig. 3 a vertical longitudinal section through the line apparatus, Fig. l the same in plan view, Fig. 5 the locomotive apparatus in side elevation, to a re- 7 duced scale,-and Fig. 6 a vertical longitudi- Specification of.

nal section throughthe line apparatus, at the moment when the latter is adjusted to indicate stop, and the locomotive apparatus is passing it. Fig. 7 shows a modified manner of constructing the line apparatus.

The station apparatus, shown in Figs. 1

and 2, consists of a drum 1O whereon a wire rope 11 may be wound. The drum 10 is connected to a ratchet wheel 12 engaged by a pawl '13. On to the'drum there is also fastened a spur gear wheel 14:, engaging a pinion 15, a crank handle 16 being fastened to the shaft of the latter. By turning this handle, the wire rope 11 may be wound around the drum 10, and the latter may be maintainedin position by means of the check pawl 13.

' The line apparatus shown in Figs. 3 and 1 is located to the right of the right track rail and is housed in a casing partly sunk into the ballast.

17, 17 indicate two adjacent sleepers on to and between which the apparatus is placed. The wire rope 11 is run from the station apparatus over guide rollers or the like to the line apparatus where it passes a vertically disposed sheave 18 carrying a counterweight 19. To the latter a vertical bar 20 is fastened, guided in its upward and downward motion by a guide bar 21. A striking piece 22 limits the upward motion of the weight 19. Above the bar 20 there is placed a lever 23, having its fulcrum upon a bolt 24 and being maintained in the position shown in Fig. 3 by means of a tension spring 25. The bolt 24: is carried by an arm 26, connected by means of a bolt 27 to a lever 28, rotatable about a fixed pin 29. The rear end 30 of the lever 28 is bent upward, as shown in Fig. 3. Behind the lever 23 there is placed another lever 31, rotatable about a fixed pin 32 and, on account of the action of gravity, normally occupying the position shown in Fig. 3.

The locomotive apparatus, as shown in Figs. 5, consists of a fixed striking piece 34, fastened to the right tender frame 33 and carrying, at the bottom a loose roller 35 and, at front, a shield or snow-plow 36. Behind this fixed striking piece there is placed an angular signal operating lever 38, having as its fulcrum a pin 37, and having its one end in linked connection, by means of a link 39, with a rod 40, passing through a tube or other guide 41, so that the upper end 42 may actuate a bell mechanism 43, causing it to sound. The connection between the angular lever 38 and the bell mechanism 43 may be of any suitable kind, and the construction of the audible signaling device as well is of no consequence for the invention as such.

The apparatus acts in the following manner: Then it is desired to have an approaching train stopped before it enters the station or block, the handle 16 is turned and thereby the wire 11 is wound on the drum 10. The counterweight 19 in the line apparatus is thus lifted until it touches the striking" piece 22. Then the pawl 13 is caused to engage the ratchet wheel 12, so that the station apparatus is locked, and the counterweight'19 remains in its upper position. The bar 20, whose upper end is rounded, in its movement lifts the lever 23 into the position indicated in dotted lines in Fig. 3. At the same time, the spring 23 is stretched. When now the train passes the apparatus, the loose roller 35 of the foremost fixed striking piece of the locomotive apparatus will hit the upwardly pointing end of the 'lever 23, and thereby it will turn it about the upper end of the bar 20, so that the spring 25 is extended still morel The rear end of the lever 23 is thereby lifted and the upwardly pointing end 30 of the lever 28 turns the lever 31 upward, as shown in Fig. 6. By this motion the lever 31 strikes the angular lever 38, causing it to turn, whereby the rod 10 is raised so as to actuate the bell mechanism 11 which is caused to sound and whose construction preferably should be such that it rings loudly and continuously for 3 or 4: minutes, so that the engineman is certain to hear it. This ringing is a signal for the engineman to stop the train at once, and then slowly to drive up to the semaphore. When the train has passed the line apparatus, the spring 25 returns the lever 23 into the position shown by dotted lines in Fig. 3, and the lever 31 drops back under the action of gravity. The apparatus is then once more adjusted to stop, until the railway employees, by disengaging the pawl 13 from the ratchet wheel 12 cause the entire apparatus to return to its position of rest, the weight 19, actuated by gravity, sinking down and drawing the wire rope 11 along.

The reason for providing a fixed as well as a movable striking piece on the frame of the tender is that the fixed striking piece, by

removing snow or otheraccidental obstructions, may provide a clear passage for the movable striking piece provided behind and, at the same time, by the assistance of the levers 23 and 28, it may cause the lever 31 to be lifted immediately behind the fixed striking piece to actuate the movable striking piece. By such an arrangement it is impossible for the movable striking piece to be actuated by accidental obstructions, such as snow, ice or the like, and thus the certainty of action of the apparatus becomes very considerable.

The modified manner of constructing the line apparatus shown in Fig. 7 difiers from the one described above by the rod 20 being connected, by a pin 50, to a lever 51, pivoted ,on a fixed pin 52 and having its other end loaded by a weight 53. The cord 11 passes the sheave 18 and is fastened, at 54, to the said lever. When the pull in the cord 11 ceases, the weight 53 will sink down and the lever 51 will lift the rod 20. The lever 23 is thereby raised into its active position, so that the apparatus becomes ready to act. When the apparatus is to be rendered inactive, a pull is exerted in the cord 11 whereby the weight 53 is lifted and the rod 20 is brought back into the position shown in Fig. 7. The spring 25 will then, as described above, force the lever 23 down into the casing of the line apparatus so as to make it entirely inactive.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a signaling device for railroad trains provided with a signal and a rigid projection; a signal-actuating member and a setting member therefor; a lever intermediary said members, one of the members permanently contacting therewith and the other member having journaled connection with said lever, manually operated means for adjusting said setting member in the path of said projection, whereby the setting member upon being struck by the projection, cotiperates with said lever to set said actuating member in position to actuate the signal; said manually operated means comprising a weighted bar for shifting the setting member and a flexible connection for actuating said bar.
